Hi out there, looking for some Takamine expertise. I’m looking at a decade old or more like new G530 and a new GD30. Is the construction and design of the GD30 any better really? The GD It’s got the pin less bridge and two piece saddle and the G530 has the traditional bridge and one piece saddle. Is this difference significant? Also, I don’t know, are there other construction differences that will matter over the long haul? Thickness of the top wood maybe or something like that? Thanks!!!
